WILLIAM B. DIMON, OF PHILADELPHIA, PENNSYLVANIA.

UMBRELLA OR PARASOL.

SPECIFICATION forming part of Letters Patent No. 403,993, dated May 28,1889.

Application filed December 18, 1888. Serial No. 293,960. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM B. DIMON, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented a new and useful Improvement in Umbrellas orParasols, of which the following is a full and complete specification,reference being had to the drawings annexed.

My invention relates to that class of umbrellas or parasols in which thelining is separate from the cover in the interior of the device.Amongits objects is to furnish a parasol or umbrella in which anornamental effect is produced by the lining, and to enable a parasol orumbrella covered with black or dark colored material to be by means ofthe air between the cover and the lining a sufficient protection againstthe hottest sun.

It consists, essentially, of a lining shaped in such a manner that thelining itself without the aid of any ribs or other support will by thecounteracting forces of its shape and the pressure of the runners andstretchers be held firm and taut in its desired shape.

Figure l is a view of a parasol or umbrella open and having the partslined on the side of the stick next the observer removed, and showingthe details of a two rib space on each side. Fig. 2 shows a section ofthe lining superposed upon a section of the cover, the sections beingformed by passing planes through two adjacent ribs and the stick. Fig. 3shows the transverse section of a secondary shape of the device; Fig. 4,the corresponding sections of the lining and cover formed in the sameway as in Fig. 2. Fig. 5 is a perspective view of a device for receivingthe lining at the top. All the parts in Figs. 1, 2, 3, and 4 are drawnmathematically correct.

Similar letters in Figs. 1 and 3 and 2 and 4 refer to similar parts.

M, Figs. 1, 3, and 5, is the stick.

N is a notch, to which the ribs l3 B B B are attached.

P is the runner.

C C C O are the stretchers, the lines I) b b b b b b b show the outlineof the cover A, and the lines 0 c c c and c c c c the outline of thelining D when the parasol or umbrella is open.

A, Figs. 2 and 4, is a section of the cover; D, a section of the lining.a a a a show the curved outline of the cover-section. (Z d d d show thecurved outlines of the lining-section. The curved outline shown in Figs.2 and 4 is such as will produce the bell-shaped effect shown in Figs. 1and 3, respectively. IVhere the parasol or umbrella is composed, asusual, of gores or sections sewed together, the section shown above willcorrespond to them, except thata strip to receive the stitches will thenbe added at the edges.

The cover A is made as usual and fastened to the ribs in the usualmanner. The lining D is then fastened to the edge of the cover andattached to the ribs up to the point E, where it is desired that thebottom part of the bell or other shaped protuberance shall begin, and tothe channeled ring N, placed between the top spring and the top notch,where the protuberance is to end. The channeled ring N may be placed onthe barrel of the top notch. It need not be made of any material placedon the stick or top notch, but may be simply an annular channel in thestick or in the barrel of the top notch.

The shape of the protuberance (shown as the shape of the inside of abell) may be changed according to the fancy of the maker by the ordinaryskill of a workman, and de pends upon the shape of the lining. However,where a curve other than a convex one is desired it is ordinarilynecessary to attach the lining at the part where it falls away most fromthe stick either directly to the ribs or indirectly to them by means ofa cord, when virtually two protuberances, the second made in the samemanner as the first, are produced.

In all cases the shape is determined in the following manner: The lengthof the lining from the point where it leaves the ribs and begins to formthe ornamental shape to the place of attachment is the length of theline outlining the desired shape when the umbrella is open, (the line 0c c c in Figs. 1 and 3,) and the circular measure of the lining at anygiven distance from its upper point of attachment is the circumferenceof a circle having a radius of the distance that point is de- IOC withthem the portion of the liningv attached.

to them, and draw the whole lining in an outward direction, while, beingof smaller circumference than the cover at any corresponding part, isdrawn inward by its shape, and the two forces thus opposed hold thelining in the shape desired. Where it is desired that parts of thelining should bulge or be loose, the width should slightly increase atthose parts. When the ornamental shape of the lining begins at a pointbelow the junction of the ribs and the stretchers O O O 0 it isnecessary that the stretchers pass through the lining to the ribs. Tomake the hole thus required as small as possible, the stretchers aremade of greater length than the distance from the top of the ribs to thestretcher-joint, so that their motion in a direction parallel to thelining be as small as possible. shown most strongly in Fig. 3.

I am aware that parasol-linings partly detached from the ribs andattached to a travnot fastened directly to the stick, have previouslybeen made. claim.

What Ido claim, and desire to secure by Letters Patent, is-

This lengthening is That, therefore, I-do not 1. A parasol or umbrellahaving the lining attached at the top immovably to the stick and atpoints nearer the bottom to the ribs or cover, and intermediatelydetached from both ribs and cover.

2. A parasol or umbrella lining attached at the top immovably to thestick and nearer .the

bottom to the ribs or cover, having the intermediate portion at allpoints of less width than the corresponding portion of the cover.

3. In an umbrella or parasol, an interior canopy having its convexitytoward the handle formed by a lining having its gores of less width inits upper parts than the gores oi the cover, said lining-gores havingtheir upper extremities turned upward toward the top notch and attachedto a channeled ring, substantially as described.

4. In an umbrella or parasol, the combination of alining covering thestretcher-joint ofthe rib with a stretcher longer than the distancebetween the top of the rib and the stretcher-joint. 1
